The present invention relates to thattype 'of automatic pistols in which the cartridge magazine is pivotably disposed within the handle of the pistol, thereby being capable 5 to transmit the pressure necessary for lreleasing the cocked hammer, to the hammer arresting mechanism. It is known that in we ons of this type the whole mechanism assumes a safety-position when the magazine is drawn out from the handle, this being evident in.view of the fact, that in such case there will be no member capable'of vtransmitting the trigger pressure to the hammer arresting mechanism.

Moreover 1t 1s evident that in the pistols in question the magazine may serve itself as a trigger.

The object of the present invention is an improvement in automatic pistols of the type mentioned above.

by way of example one embodiment of the invention partly in section. resents a detail:

1 is the body of the pistol, forming the handle at 2, and provided with thevbarrel 3 and the breach-slide 4, which latter contains the firing pin 5. Within the rear part of the handle 2 is removably disposed in any usual manner, for instance by the intermediary of the safety bolt 6 and of a pin 7, a piece 8 capable to pivot rearwardly around the pin 7 and supporting the hammer 9 and the hammer actuating mechanism.

The handle 2 contains moreover a mag'- azine 10, capable of pivoting within said handle in lthe known manner, that is to say, -a'round'an axis passing through the point 11, and in the senses of the arrows 12 and 13, the angular displacement of the magazine in the 'sense of arrow 12 being obtained by manual pressure, whereas its angular dis- Vplacement in the sense of arrow 13 is assured' by the action of the magazine catch 14actuated by a spring 15.-

According to the present invention the hammer 9, having its pivot at 16, is actuated by the main spring 17 through the intermediary of a rod 18, which on the one hand, is guidedA at its interior extremity in a suitably perforated projection 19 of the piece 8, and which onthe other hand, isarticulated to the hammer 9 at a point 20, whichlatter is situated, at the cocked position of the hammer (that shown in the drawing) at the left The annexed drawing Figure 1 represents Figure 2 rephand side of the plan my passing through the hammerpivot 16 and through the center of the guiding hole within the projection 19. The corresponding axial'plan of the rod 18 has been represented by the line wz. Thus 1t 1s lobvious that ,in the cocked position of lthe hammer, theI compressed main spring tends to provoke a rotation of the hammer,

in a clockwise direction, such clockwise displacement of the hammer being limited by the shoulder 21 of piece 8, serving as an abutment for the projection 22 of the hammer. Thus the hammer will be maintained in the cocked position by the pressure of the main' 70 spring. i

The hammer 9 ismoreover provided with a shoulder 23, formlng a suitable face at 24. 0n the other hand the main body 1` of the pistolis cut away on both sides at 25, thereby. permitting a pressure to be exerted directly upon the front face 26 of the cartridge magazine.

As soon as the breech slide 4 has assumed its closed position it will be sulicient to 80 exert a pressure upon the front face 026 of the cartridge magazine.'

This latter will transmit the pressure to the shoulder 2310i the hammer, thereby angularly displacing this latter in an anticlockwise direction. As soon as the point of articulation 20 of the rod 8'to the hammer 9 passes from the left to the right of the line my, the pressure of the main spring 17 causes lthe hammer 9 to vexecute its blow against the firing pin 5,

The lower extremity of the main spring 17 may press against the projection 19 of part 8 through the intermediary of a washer or annular plate 27 seated upon a spherical or equivalent perforatedpiece -28 supported by the. projection 19.

It is evident that the seat of the lower extremity of the main spring. may be as well constructed as shown in Figure 2 which needs no further explanation.

As mentioned above the shoulder 23 of the hammer forms a suitable face orgedge 24.v The. destination of this latter is the following: when' the hammer Ais -in a cooked position and the magazine is introduced in the handle of thepistol it may occur .that the right hand upper .edge of the magazine comes into contactl with thel hammer, such contact being capable of producing the involuntary liberation Aof the har'nmer. Now the'face 24 is disposed in such Aa manner, that` any presmasias 'sure exerted bythe magazine in theV circum-l.

the intermediary'ofwhich the hand pressurel .iscommuncated to the hammer locking thereby rovoking the liberation andthe blow of t e hammer, the handle,

mechanism of the pistol being for,v this-purpose suitably cut away at the front of the magazine, a

v hammer ivoted within the handle 'part of 15 the'pisto a suitably perforated projection upon said handle part, a rodsuitably guided one of its extremities within said perforated projection, and articulated byits other "extremityto'fthe hammer at a point, which at :the cockedpositionfof -the hammer is d1s- V.posed atlone s1de for instance in -front of the line passing through the pivot center of the hammer and' through thelcenter of the hole within said projection, this cocked position being 'determined throu h the contact between the suitably form hammer headand a shoulder of said handle part a sp 'y com# i e one bined with said rod and pressing on hand-against said rojection of said handle part and on the ot er hand through the intermediary of said rod a ainst the hammer at said point, thereby maintaining the hammer inthe cocked position, and a shoulder upon said hammer serving to transmit the angular displacement of the magazine to the hammer, the displacementof the latter causing the' said polnt of :articulation tomove from the one side of saidlline 'to its other side thus provoking the blow of thehammen'.

' 2. Automatic pistol according to claim 1,

characterized by the fact that the lower portion of said shoulder ofthe hammer lis pro-- led in such a mannerfa's to obviate the liberation ;of the cocked hammer through the upper corresponding part ofthe magazine,

vduring the introduction of this latter within the handle of the pistol.V
